NAME
       mkpasswd - Overfeatured front end to crypt(3)

SYNOPSIS
       mkpasswd PASSWORD SALT

DESCRIPTION
       mkpasswd  encrypts  the  given password with the crypt(3) libc function
       using the given salt.

OPTIONS
       -S, --salt=STRING
              Use the STRING as salt. It must not  contain  prefixes  such  as
              $1$.

       -R, --rounds=NUMBER
              Use NUMBER rounds. This argument is ignored if the method chosen
              does not support  variable  rounds.  For  the  OpenBSD  Blowfish
              method this is the logarithm of the number of rounds.

       -m, --method=TYPE
              Compute  the  password  using  the TYPE method.  If TYPE is help
              then the available methods are printed.

       -5     Like --method=md5.

       -P, --password-fd=NUM
              Read the password from file descriptor NUM instead of using get-
              pass(3).   If the file descriptor is not connected to a tty then
              no other message than the hashed password is printed on stdout.

       -s, --stdin
              Like --password-fd=0.

ENVIRONMENT
       MKPASSWD_OPTIONS
              A list of options which will be evalued before the  ones  speci-
              fied on the command line.

BUGS
       If  the --stdin option is used, passwords containing some control char-
       acters may not be read correctly.

       This programs suffers of a bad case of featuritis.
